Using the Microsoft for Google Workspace Migration Addin and only MY user will come over...please help

Question

I'm not sure I have the correct permissions to do this. I have Global Admin rights in Google workspace. In O365 online I have MS business premium and have mapped the google emails to the microsoft emails correctly. Mine came over great, 11k files moved over. Every other user it just reads "General failure — please try again". My guess is that my permissions need to be adjusted in Exchange Admin. Any thoughts? Thanks in advance, there are a total of 7 users, including mine. My account had the most data and that finished successfully. The other 6 will be quick but I just need to get them started. Thanks in advance!

Hi @Stacey Egerton

Thank you for posting your question in the Q&A Forum. It’s great to hear that your own mailbox migrated successfully.

For the remaining six users, the “General failure - please try again” message can sometimes be related to permission settings on the Microsoft 365 side. While your Google Workspace Global Admin role covers the source, the Microsoft 365 Global Admin role doesn’t always automatically provide access to other users’ mailboxes for migration purposes.

One approach that often helps is ensuring the account performing the migration (likely yours) has the ApplicationImpersonation permission in Exchange Online. Here’s a suggested guideline you might consider:

1. Role Verification: Confirm that the account running the migration has been added to an Exchange Online Role Group that explicitly includes the ApplicationImpersonation permission.
2. Best Practice: A straightforward method is adding your migration account to the Organization Management role group within the Exchange Admin Center (or via Exchange Online PowerShell). This role group inherently provides the required access.
3. Propagation Time: After updating permissions, it’s usually helpful to wait 30-60 minutes for the changes to fully propagate across Microsoft 365.
4. Retry Migration: Once permissions are verified and sufficient time has passed, try rerunning the migration batch for the six remaining users.

Hopefully, this provides some guidance to help get the rest of the users’ mailboxes migrated smoothly.

It sounds like you are experiencing issues with migrating other users' data from Google Workspace to Microsoft 365. Since your account migrated successfully, it indicates that your permissions are likely set correctly. However, for the other users, you may need to ensure that they have the appropriate permissions configured in both Google Workspace and Microsoft 365.

Here are some steps you can take to troubleshoot and resolve the issue:

1. Check Permissions in Google Workspace: Ensure that the accounts you are trying to migrate have the necessary permissions. They should have read access to their Google accounts.
2. Verify IMAP Settings: Make sure that IMAP access is enabled for each user in Google Workspace. You can check this in the Google Admin console under the user's settings.
3. Provision Microsoft 365 Mail Users: Ensure that the users are properly provisioned in Microsoft 365. This includes confirming that their primary email addresses are set up correctly and that they have the necessary proxy addresses configured.
4. Review Migration Logs: Check the migration logs in the Exchange Admin Center for any specific error messages related to the failed migrations. This can provide more insight into what might be going wrong.
5. Incremental Sync: If you have already attempted to migrate the users, consider performing an incremental sync after addressing any issues found in the previous steps.

If after checking these areas the problem persists, you may want to consult the Microsoft documentation or support for further assistance.
